The parameters in this table are updated when a measurement
request is made using the xdsl2LineCmndConfBpsc object.
Note that a bits-per-subcarrier measurement is also performed
during a line diagnostic procedure. This table provides an
additional mechanism to fetch the bits-per-subcarrier data. This
additional mechanism is provided so that bits-per-subcarrier
data may be fetched without forcing the line into no power state.
This is useful because the bits-per-subcarrier allocation may be
adjusted at Showtime due to rate adaption and bit swapping.
The implementation of this additional mechanism for measuring
bits per subcarrier is not mandatory."

highest supported upstream and downstream subcarriers according
to the selected implementation profile. For ADSL, NSus is equal
to NSCus-1 and NSds is equal to NSCds-1.
One index of this table is an interface index where the interface
has an ifType of vdsl2(251). A second index of this table is the

DESCRIPTION
"The bits allocation per subcarrier. An array of 256 octets

subcarriers. When more than 512 subcarriers are supported, the
status information is reported through multiple (up to 8)
segments. The first segment is then used for the first 512
subcarriers. The second segment is used for the subcarriers
512 to 1023 and so on.
The aggregate number of utilized nibbles in the downstream
direction (in all segments) depends on NSds; in the
upstream direction, it depends on NSus.
This value is referred to here as NS. The segment number is in
xdsl2SCStatusSegment.
Nibble i (0 <= i < MIN((NS+1)-(segment-1)*512,512)) in each
segment is set to a value in the range 0 to 15 to indicate that
the respective downstream or upstream subcarrier j
(j=(segement-1)*512+i) has the same amount of bits
allocation."

DESCRIPTION
"Row Status. The SNMP agent will create a row in this table
for storing the results of a measurement performed on the
associated line, if the row does not already exist.
The SNMP manager is not permitted to create rows in this table or
set the row status to 'notInService'. In the first case,
if the SNMP manager tries to create a new row, the SNMP agent
responds with the value 'noCreation' in the error status
field of the response-PDU. In the latter case, the SNMP agent
responds with the value 'wrongValue' in the error status
field of the response-PDU.
The SNMP agent may have limited resources; therefore, if multiple
rows coexist in this table, it may fail to add new rows to this
table or allocate memory resources.
If that occurs, the SNMP agent responds with the value
'noResources' (for the xdsl2LineCmndConfBpscFailReason
object in xdsl2LineTable).
The management system (the operator) may delete rows from this
table according to any scheme. For example, after retrieving
the results.
When the SNMP manager deletes any row in this table, the SNMP
agent MUST delete all rows in this table that have the same
ifIndex value."

DESCRIPTION
"Row Status. The SNMP agent will create a row in this table

When a row is created in this table, the SNMP agent should also
create corresponding rows in the tables xdsl2SCStatusBandTable and
xdsl2SCStatusSegmentTable.
The SNMP manager is not permitted to create rows in this table or
set the row status to 'notInService'. In the first case,
if the SNMP manager tries to create a new row, the SNMP agent
responds with the value 'noCreation' in the error status
field of the response-PDU. In the latter case the SNMP agent
responds with the value 'wrongValue' in the error status
field of the response-PDU.
When a row is deleted in this table, the SNMP agent should also
delete corresponding rows in the tables xdsl2SCStatusBandTable and
xdsl2SCStatusSegmentTable.
The SNMP agent may have limited resources; therefore, if multiple
rows coexist in this table, it may fail to add new rows to this
table or allocate memory resources for a new DELT process. If
that occurs, the SNMP agent responds with either the value
'tableFull' or the value 'noResources' (for
the xdsl2LineCmndConfLdsfFailReason object in xdsl2LineTable).
The management system (the operator) may delete rows from this
table according to any scheme. For example, after retrieving the
results."
